What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: To evaluate the acute effects of intensity-modulated radiotherapy (IMRT) on sexual function, sex hormone levels, and psychological status in male patients with nasopharyngeal carcinoma, and to further assess the associations between changes in sexual function and hormonal and psychological parameters. Methods: Eighty-five male patients with nasopharyngeal carcinoma who received IMRT were retrospectively included. Erectile function was evaluated using the International Index of Erectile Function-5 (IIEF-5), and ejaculatory function was assessed using the Chinese Index of Premature Ejaculation (CIPE). Serum sex hormone levels, including follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T), estradiol (E2), prolactin (PRL), and progesterone (P), as well as psychological status assessed by the Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS), were extracted from clinical records at baseline and 30 days after radiotherapy. Paired comparisons (paired t-tests or Wilcoxon signed-rank tests) and Pearson correlation analyses were performed. Results: Within 30 days following IMRT, both IIEF-5 and CIPE scores significantly decreased compared with baseline (both p < 0.001). Post-treatment levels of FSH and PRL were significantly increased, whereas T and P levels were significantly decreased (all p < 0.001). No significant changes were observed in LH or E2 levels. Correlation analyses revealed weak associations between sexual function scores and sex hormone levels (|r| < 0.2). SAS and SDS scores did not change significantly after radiotherapy, and psychological scores showed a weak negative correlation with sexual function scores. Conclusion: In male patients with nasopharyngeal carcinoma, IMRT is associated with a significant decline in sexual function during the acute phase, accompanied by alterations in sex hormone profiles. Sexual function changes showed weak associations with both hormonal and psychological factors.
